基座20架設於桌面或其他支撐面上,用以供工件置放,基座20的一後端設置一支撐架22,支撐架22由基座20朝上方延伸。The base 20 is mounted on a table top or other supporting surface for the workpiece to be placed. A rear end of the base 20 is provided with a support frame 22, and the support frame 22 extends upward from the base 20.
滑動台30具有至少一滑動桿32與一固定座34。滑動桿32可沿本身之軸向移動地穿設於基座20上的支撐架22,使得滑動台30可相對於支撐架22線性滑動一預定的行程,以達到預定的一鋸切行程;固定座34具有一固定端部342及一延伸部348,固定座34之固定端部342固定於滑動桿32之一端,使得固定座34可受滑動桿32之帶動而相對基座20移動,此外,固定座34之固定端部342具有一前端部344及一後端部346,在遠離滑動桿32之前端部344定義出一基準面P,基準面P實質上垂直於滑動桿32之軸向,而在固定端部342在接近滑動桿32之後端部346定義出一後平面PR,後平面PR實質平行於基準面P;延伸部348自固定端部342以大致延著滑動桿32之軸向的方向朝遠離固定端部342的後端部346往後延伸。The slide table 30 has at least one slide bar 32 and a mount 34. The sliding rod 32 can be movably disposed in the axial direction of the support frame 22 on the base 20 such that the sliding table 30 can linearly slide relative to the support frame 22 for a predetermined stroke to achieve a predetermined sawing stroke; The seat 34 has a fixed end portion 342 and an extending portion 348. The fixed end portion 342 of the fixing base 34 is fixed to one end of the sliding rod 32, so that the fixing seat 34 can be moved by the sliding rod 32 to move relative to the base 20, and The fixed end portion 342 of the fixing base 34 has a front end portion 344 and a rear end portion 346. Before the sliding rod 32 is away from the sliding rod 32, a reference surface P is defined. The reference surface P is substantially perpendicular to the axial direction of the sliding rod 32. While the fixed end 342 defines a rear plane PR at the end 346 near the sliding rod 32, the rear plane PR is substantially parallel to the reference plane P; the extension 348 extends from the fixed end 342 substantially in the axial direction of the sliding rod 32. The direction extends rearwardly away from the rear end portion 346 of the fixed end portion 342.
鋸切裝置40具有一鋸臂42與一鋸片44。鋸臂42藉由一轉軸46樞設於固定座34之延伸部348,轉軸46位於固定端部342的後平面PR的後方;鋸片44具有一半徑R,並藉由一心軸442樞設於鋸臂42而可受鋸臂42之帶動於一最高位置P1與一最低位置P2之間相對固定座34之基準面P上下作動,同時,鋸片44與固定座34的相對位置採適當的配置,使兩者不致產生干涉,當鋸片44位於最高位置P1時,如第一圖所示,鋸片44與基準面P之間會形成相交,當鋸片44位於最低位置P2時,如第三圖所示,鋸片44與基準面P會形成相交,此時,心軸442至轉軸46具有一水平距離L1,轉軸46至基準面P具有一水平距離L2,基準面P至心軸442具有一水平距離L3,三者水平距離的關係為L3=L1-L2,即基準面P至心軸442的水平距離L3等於心軸442至轉軸46的水平距離L1減去轉軸46至基準面P的水平距離L2,即L3小於鋸片半徑R。亦可設計使L3等於鋸片半徑R,則鋸片44與基準面P之間會形成相切。The sawing device 40 has a saw arm 42 and a saw blade 44. The saw arm 42 is pivotally disposed on the extending portion 348 of the fixing base 34 by a rotating shaft 46. The rotating shaft 46 is located behind the rear plane PR of the fixed end portion 342. The saw blade 44 has a radius R and is pivoted by a spindle 442. The saw arm 42 can be actuated by the saw arm 42 between a highest position P1 and a lowest position P2 with respect to the reference plane P of the fixed seat 34, and the relative position of the saw blade 44 and the fixed seat 34 is appropriately configured. So that the two do not interfere, when the saw blade 44 is at the highest position P1, as shown in the first figure, the saw blade 44 and the reference plane P will form an intersection, when the saw blade 44 is at the lowest position P2, as in the first As shown in the three figures, the saw blade 44 intersects with the reference plane P. At this time, the mandrel 442 to the rotating shaft 46 have a horizontal distance L1, and the rotating shaft 46 to the reference plane P have a horizontal distance L2, and the reference plane P to the mandrel 442 There is a horizontal distance L3, and the relationship between the three horizontal distances is L3=L1-L2, that is, the horizontal distance L3 of the reference plane P to the mandrel 442 is equal to the horizontal distance L1 of the mandrel 442 to the rotating shaft 46 minus the rotating shaft 46 to the reference plane P. The horizontal distance L2, that is, L3 is smaller than the blade radius R. It is also possible to design such that L3 is equal to the blade radius R, and a tangent is formed between the saw blade 44 and the reference plane P.
護蓋裝置50具有一護蓋51、一支撐座52,以及一連桿53。護蓋51樞設於鋸臂42且罩設鋸片44;支撐座52設於固定座34之頂面且具有一導槽54及一頂抵槽55,導槽54呈長條狀,頂抵槽55具有一第一傾斜段56及一第二傾斜段57,第一傾斜段56由一相對趨近基準面P的方向朝遠離基準面P的方向傾斜地往下延伸,第二傾斜段57與該第一傾斜段56連通,且自第一傾斜段56之底端由相對遠離該基準面P的方向朝接近基準面P的方向傾斜地往下延伸;連桿53之一端樞設於護蓋51,連桿53之另一端自其一側面一體地突伸出一導引部58及一抵頂部59,其中的導引部58可滑移地嵌設於導槽54內,抵頂部59可滑移地嵌設於頂抵槽55內。The cover device 50 has a cover 51, a support base 52, and a link 53. The cover 51 is pivotally disposed on the saw arm 42 and covers the saw blade 44. The support base 52 is disposed on the top surface of the fixing base 34 and has a guiding groove 54 and a top abutting groove 55. The guiding groove 54 is elongated and topped. The groove 55 has a first inclined section 56 and a second inclined section 57. The first inclined section 56 extends obliquely downward from a direction approaching the reference plane P with respect to the direction approaching the reference plane P, and the second inclined section 57 is The first inclined section 56 is connected, and the bottom end of the first inclined section 56 extends obliquely downward from the direction away from the reference plane P toward the reference plane P; one end of the connecting rod 53 is pivotally disposed on the cover 51. The other end of the connecting rod 53 integrally protrudes from a side surface thereof with a guiding portion 58 and an abutting top portion 59. The guiding portion 58 is slidably embedded in the guiding groove 54 and is slidable against the top portion 59. The ground is embedded in the top abutment groove 55.
在使用前,如第一圖所示,鋸片44位於最高位置P1,此時的連桿53之抵頂部59位於頂抵槽55之第一傾斜段56的頂端。使用者欲使用時,將鋸臂42向下壓朝基座20趨近,當鋸片44受到鋸臂42的帶動而從最高位置P1朝最低位置P2偏轉時,如第二圖所示,連桿53之抵頂部59會沿著頂抵槽55之第一傾斜段56的內側面往下移動,連桿53之導引部58則是沿著導槽54往後移動,此時的連桿53會利用本身之抵頂部59與頂抵槽55之第一傾斜段56之間的頂抵關係來產生拉動護蓋51的力量,讓護蓋51開始相對鋸片44樞轉而讓鋸片44增加外露的部份。Prior to use, as shown in the first figure, the saw blade 44 is at the highest position P1, at which point the abutment top 59 of the link 53 is located at the top end of the first inclined section 56 of the top abutment groove 55. When the user wants to use, the saw arm 42 is pressed downward toward the base 20, and when the saw blade 44 is driven by the saw arm 42 and deflected from the highest position P1 toward the lowest position P2, as shown in the second figure, The abutting top 59 of the rod 53 moves downward along the inner side surface of the first inclined section 56 of the top abutment groove 55, and the guiding portion 58 of the connecting rod 53 moves backward along the guiding groove 54, the connecting rod at this time 53 will utilize its own abutting relationship between the top 59 and the first inclined section 56 of the abutment groove 55 to create the force to pull the cover 51, causing the cover 51 to begin pivoting relative to the blade 44 to allow the blade 44 to be pivoted. Increase the exposed part.
當鋸臂42持續向下偏轉時,連桿53之抵頂部59會沿著頂抵槽55之第二傾斜段57的內側面往下移動,並同時保持與頂抵槽55之第二傾斜段57之間的頂抵關係,使得連桿53將持續拉動護蓋51而讓護蓋51相對鋸片44樞轉的角度更大,鋸片44所外露的部份也就更多,當連桿53之抵頂部59位於頂抵槽55之第二傾斜段57的底端時,如第三圖所示,鋸片44位於最低位置P2而與固定座34之基準面P形成相交,此時的鋸切裝置40即可透過滑動桿32來相對基座20移動,當移動鋸切裝置40至鋸切行程的最末端,此時固定座34之固定端部342的後端部346實質抵靠基座20的支撐架22,如第四圖所示,並在移動的過程中藉由鋸片44的外露部份對工件進行鋸切加工。When the saw arm 42 continues to deflect downward, the abutting top 59 of the link 53 moves down along the inner side of the second inclined section 57 of the top abutment groove 55 while maintaining the second inclined section of the abutment groove 55. The abutting relationship between 57 causes the link 53 to continue to pull the cover 51 to make the cover 51 pivot at a greater angle relative to the saw blade 44, and the exposed portion of the saw blade 44 is more. When the abutting top 59 of the 53 is located at the bottom end of the second inclined section 57 of the top abutment groove 55, as shown in the third figure, the saw blade 44 is located at the lowest position P2 and intersects with the reference plane P of the fixed seat 34, at this time The sawing device 40 can be moved relative to the base 20 through the sliding rod 32. When the sawing device 40 is moved to the extreme end of the sawing stroke, the rear end portion 346 of the fixed end portion 342 of the fixing seat 34 is substantially abutted against the base. The support frame 22 of the seat 20, as shown in the fourth figure, is sawed by the exposed portion of the saw blade 44 during the movement.
藉此,本發明之圓鋸機10的設計可以讓鋸切裝置40在相同的鋸切行程之下縮短從滑動台30所伸出的距離,如此即可有效減少整體材積且力臂長度縮短而降低使用時所產生的晃動問題,用以達到增加鋸切精度的功效。另外,本發明之圓鋸機10所提供的連桿53同時具有導引部58及抵頂部59,使得連桿53之導引部58及抵頂部59可以同時隨著連桿53相對支撐座52偏擺,因而能夠很順暢地配合支撐座52之導槽54及頂抵槽55來拉動護蓋51產生樞轉,以達到增加作動順暢性之目的。Thereby, the design of the circular sawing machine 10 of the present invention allows the sawing device 40 to shorten the distance extended from the sliding table 30 under the same sawing stroke, thereby effectively reducing the overall volume and shortening the length of the arm. Reduce the sloshing problem caused by the use, to achieve the effect of increasing the precision of sawing. In addition, the connecting rod 53 provided by the circular sawing machine 10 of the present invention has both the guiding portion 58 and the abutting top 59, so that the guiding portion 58 and the abutting top portion 59 of the connecting rod 53 can simultaneously follow the connecting rod 53 with respect to the supporting seat 52. The yaw can be smoothly matched with the guide groove 54 of the support base 52 and the top abutment groove 55 to pull the cover 51 to pivot, so as to increase the smoothness of the operation.
